Batch delete exif info
The other ExifTool suggestions are great if you want to remove or change specific sections. But if you want to just remove all of the metadata completely, use this (from the man page):
exiftool -all= dst.jpg
Delete all meta information from an image.
You could also use jhead, with the -de flag:
-de Delete the Exif header entirely. Leaves other metadata
sections intact.
Note that in both cases, EXIF is only one type of metadata. Other metadata sections may be present, and depending on what you want to do, both of these programs have different options for preserving some or removing it all. For example, jhead -purejpg
strips all information not needed for rendering the image.
The EXIF handling tool exiv2
has a command for deleting EXIF data:
exiv2 rm image.jpg
removes all EXIF data from the image.
To remove EXIF data from all JPEG images in the current directory, use
exiv2 rm *.jpg
To remove EXIF data from all JPEG images in the current directory, and all subdirectories of it recursively, use:
find . -type f -iname '*.jpg' | xargs exiv2 rm
It is a good idea to test the command before.
To see which files are found:
find . -type f -iname '*.jpg' | less
To see which commands will be executed:
find . -type f -iname '*.jpg' | xargs echo exiv2 rm | less
Note the echo
inserted before exiv2
to print the command, instead of running it.
You should look at some opensource tools like exiftool. There is a lot of option (for exif, xmp, iptc).

The only thing you should do next is to write a tiny script that lists your files (jpg) and does the stuff. To remove the content of a field you'll have to set it to " ^" ; like the following example:
